Featuring 4K bytes of Flash programmable and erasable read-only memory, a 24 MHz operating frequency, and an operating voltage range of 2.7V to 6V, this microcontroller delivers the reliability and adaptability necessary for control applications and consumer electronics. It offers 15 I/O pins, 2 timers/counters, a UART for serial communication, and 128 bytes of internal RAM for data storage, providing a comprehensive and capable platform for a variety of projects. Additionally, its 2-level interrupt priority structure and programmable clock divider ensure efficient handling of interrupts and system clock generation. Whether you're developing a control system, a consumer electronics device, or any other embedded application, the AT89C4051-24PI microcontroller offers the performance, flexibility, and features required to bring your project to fruition

Features

• 4K bytes of Flash, 128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five-vector, two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and clock circuitry. In addition, the AT89C4051 is designed with static logic for operation down to zero frequency and supports two software-selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.
